Abstract (en)
A gas turbine engine (20) comprises a compressor rotor including blades (105) and a disk (104), with a bore defined radially inwardly of the disk (104), and a combustor (112). A tap (116) directs the products of combustion first to a valve (120) and then into the bore of the disk (104). At least two temperature sensors (204,206) sense a temperature of the products of combustion downstream of the valve (120). A control (200) compares sensed temperatures from the at least two temperature sensors (204,206) to ensure the at least two temperature sensors (204,206) are functioning properly. The sensed temperatures are utilized to control the valve (120). A method of operating a gas turbine engine (20) is also disclosed.
